Hello all. Put my F1 on the track this weekend and found I had a hell of a time keeping the rear planted. Running 571/572 pits outdoors and added 28g of weight to the rear. Didn't feel like it was much help. Towards the later part of the main, it felt like the tires were finally gripping. Do the pits take about a race day (2 heats/1 main) or so to get "broken" in? Waiting on a local guys successful setup sheet to compare but from initial looks may be only fluids to change. Thanks.
